Health-related quality of life among Malaysian pediatric survivors of central nervous system tumor.

ABSTRACT

Pediatric central nervous system tumor survivors (CNSTS) experience late effects that may affect their health-related quality of life (HRQOL). The study aims: i) compare HRQOL among Malaysian CNSTS with acute lymphoblastic leukemia survivors (ALLS) and healthy children, and ii) explore factors associated with low HRQOL. We performed a comparative cross-sectional HRQOL study of 46 CNSTS aged 5-18 years and 90 ALLS (age and gender-matched) who completed treatment for >1 year, and a published cohort of healthy children. Pediatric Quality of Life Inventory (PedsQL) was used for all groups and PedsQL Cancer Module for CNSTS and ALLS. Multiple regression analysis was used to determine factors associated with low HRQOL. Mean PedsQL total scale score, physical health score and psychosocial health score of CNSTS were 69.0 (SD 20.3), 68.7 (SD 27.9) and 69.2 (SD 19.2) respectively. These scores were significantly lower in all domains particularly in teenagers compared with healthy children and ALLS. The median PedsQL Cancer Module score of CNSTS was significantly lower than ALLS in total scale, cognitive problems and communication. Physical impairment was associated with lower PedsQL scores in all 3 domains; special education placement was associated with lower PedsQL total scale and physical health scores and clinically significant internalizing behavioral difficulties score was associated with lower PedsQL psychosocial health scores. CNSTS reported lower PedsQL scores in all domains than ALLS and healthy children. Clinicians need to be vigilant of HRQOL needs among CNSTS, especially those with risk factors of special education needs, physical impairment, and internalizing behavioral difficulties.
